PRINTING-PRESS ATTACHMENT.

To all whom it may concern:

Be it known that I, lViLLiAM 1t. HILDE- iinAND, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Printing- Press Attachments, of which the following is a specification.

This invention relates to printing press attachments and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide an attachment adapted to be applied to the frame of a press and which may be adjusted in its position. The said attachment carries the delivery mechanism of the press whether the said mechanism be the usualfly fingers or grass hopper, or both. Longitudinally extensible means is provided for operating the delivery mechanism from a moving part of the press. The said attachment may be so positioned on the frame of the press as to cause the delivery mechanism to deposit the printed sheets upon a table mounted upon the frame of the press or upon a truck located at the end of the frame of the press.

Another object of the invention is to provide a wheel mounted truck upon which is movably mounted a table adapted to receive the sheets of paper from the press after the printing has been. applied to the same. Means is provided for gradually lowering the table in its supporting frame so that as the sheets of printed paper are piled thereon and the table descends the uppermost surface of the uppermost sheet of paper is supported approximately at the same place or level as the uppermost sheets of all-preceding sheets of paper were supported when they were positioned upon the pile of sheets.

Means is provided, for automatically lowering the table as above indicated and this means is operated from any suitable movable part of the press.

In the accompanying drawings: Figure 1 is a side elevation of a cylinder press with the attachment appliedi Fig. 2 is a perspective view of the truck. Fig. 3 isa hori zontal sectional view of the truck cut on the line 3-3 of Fig. 1.

As shown in the accompanying drawing the press 10 may be of any conventional form but as illustrated it is of that pattern generally known as a. cylinder press. The

The attachment comprises a frame or head 9 which is adjustably mounted upon the frame of the press 10 in a manner which will be hereinafter explained. A grass-hopper'mechanism 13 may be mounted upon the frame or head 9 and a longitudinally extensible rod 14 is provided for operating the said grasshopper mechanism in the usual manner. As the grass-hopper 13 and the connecting parts form n0 portion of the present invention further description of the same is unnecessary. The sections of the rod 14; are arranged to telescope with relation to each other and the said rod 14 may be operatively connected in any suitable manner with any rotating or movable part of the press 10 as most clearly indicated in Fig. 1 of the drawing.

A fly finger shaft 8 is journaled upon the head or frame 9 and"ta'rries fly fingers (not shown) of any conventional'or usual form. A longitudinally extensibie rod 15 is pro vided for operating the fly finger shaft 8 and the sections of the said rod 15 are arranged to telescope with relation to each other. The rod 15 is also adapted to be operated by a movable part of the press 10 as indicated in Fig. 1. of the drawing. Rack bars 17 are mounted upon the frame of the press 10 and extentl back to the set of jtapes 11 as indicated in 1 of the drawing. Parallel tracks 18 are fixed at one end with relation to the frame or head 9 and along these tracks the head 16 of the grasshopper mechanism is adapted to travel. A shaft 21 is journaled for rotation upon the frame 9 and extends transversely across the rack bars 17. This shaft may be provided with a squared end to which a crank handle may be applied for rotating the same. Gear wheels 22 are mounted upon the shaft 21 and mesh with the teeth of the rack bars 17. Therefore it will be seen that by employing the set of tapes 12 and by positioning the head or frame 9 at the outer ends of the rack bars 17 as shown in Fig. 1 the grasshopper 13 may be employed for removing the sheets of printed paper from the tapes 12 to a wheel mounted truck hereinafter to be described or should it be desired to use nism 13 is operated by the rod 14'.

W en t is desii ed that the printed sheets be deposited upon the table usually mounted upon the frame of the press the tapes 12 are removed and by turning the shaft 21 the head or frame 9 is moved toward the inner ends of the rack bars 17 and consequently the delivery mechanisms receive the printed .sheetsof paper from the tapes 11 and deposit them upon the table which is located between the rack bars 17 in the usual man ner. As the head 9 is moved toward the inner ends of the rack bars 7 the sections of the rods 14 and 15 are permitted totelescope with relation to each other whereby the said rods are shortened and one or the other may be used for operatingthe delivery mechanism mounted on the head 9.

When the head or frame 9 is positioned at the outer ends of the rack bars 17 as shown in Fig. 1 a wheel mounted truck indicated at 18 may be employed for receiving the printed sheets. Said truck 18 is mounted upon wheels or rollers 19 and the upper portion of the said truck is adapted to be receivcd between the tracks 18 asindicated in F 1 of the drawings. Vertically disposed shafts 23 are journaled in the upper and lower portions of the frame of the truck 18 and the said shafts are externally threaded as at 24. Bars 25 are provided at points between their ends with threaded bearings 26 which engage the threads 24 upon the shafts The end portions of the bars 25 are received in guides 27 provided at the sides of the truck 18. Beveled pinions 28 are fixed to the upper portions of the shafts 23 and mesh with beveled pinions 29 carried at the ends of the horizontal shafts 3O journaled in the upper portion of the truck 18. A shaft 31 is journaled at the upper portion of the truck 18 and extends transversely across the same the'said shaft being provided at its opposite end portions with beveled pinions 32 which mesh with beveled pinions 33 mounted upon the drafts 30. A disk 34 is mounted upon oneLsnd of the shafts 31 and is pro- "vided with an internal set of gear teeth 35.

A crank 36 is pivoted upon the end portion of the shaft 30 and is provided with a spring pressed pawl 37 which engages the gear teeth 36 of the disk 34. A rod 38 is adapted to connect the free end portion of the crank 36 with any movable part of the press 10 whereby the said rod 38 isreciprocated when the press is operated.

The reciprocation of the rod 38 swings the crank 36 and the pawl 37 thereof engages, the teeth 35 of the disk 34 and turns the said pawl. together with the shaft 31. As the shaft. 31 turns the gear wheels 32 turn the pinions 33 which in turn partially rotate the shaft 30. Through the intermeshing gear pinions 28 and 29 the shafts 23 are turned and inasmuch as the said shafts have screw thread engagement with the bars the said bars are caused to descend along the vertical sides of the truck 18. In-the meantime during the operation of the press 10 the printed sheets are passed from the tapes 11 upon the tapes 12 and are removed by the grass-hopper 13 and deposited upon the table 39 which is carried by the bars 25. Thus it will be seen that as the sheets are successively placed in a pile upon the table the table gradually descends and consequently during the printing of a number of sheets the uppermost surface of the uppermost sheet upon the pile of sheets which rests upon the table 39 remains at the same level or plane as that which was occupied by all of the uppermost surfaces of the preceding sheets. Therefore when all of the sheets have been printed the truck 18 may be moved away from the frame of the press 10 upon its supporting wheels 19 and thus the printed sheets are not damaged by manual handling immediately after printing in order vto remove them from the press and they may remain upon the table 39 until they have dried sufliciently to be handled without danger of damage.

Having described the invention what is claimed is l. A press attachment comprising a head, a delivery mechanism mounted upon the head, said head being mounted for bodily movement toward and from the press whereby the delivery device may deliver sheets upon a table adjacent to or spaced from'the press and an adjustable means for operating the said delivery mechanism from a movable part of the press at the position to which the head is adjusted.

2. A press attachment comprising a head, rack bars mounted upon the frame of the press, gear wheels carried by the head and meshing with the rack bars to move the head along the frame of the press, a delivery mechanism mounted upon the head, said head being mounted for bodily movement toward and from the press whereby the delivery device may deliver sheets upon a table adjacent to or spaced from the press and adjustable means for operating the delivery mechanism from a movable part of the press at the p0- sition to which the head is adjusted.
